Abstract: A composite fishing line comprising a core and braided jacket the core being made of material which will break under a predetermined tensile loading of the line, said braided jacket being made of a different material which does not break under said predetermined tensile loading and having a braid tightness which permits reoccurrent breaks in the core under the reoccurrence of said tensile loading without affecting the utilization of the line.

Abstract: A rotary cutting assembly with an automatic filament feed. The assembly includes a driven member which is coupled to a drive source and contains a storage spool for the cutting line. The line or filament is automatically advanced from the spool upon displacement of the same through engagement of a ground engaging hub with a surface. Such displacement causes operation of a ratchet means mounted in part on the movable spool or associated therewith and in part on the driven member to permit a limited rotary displacement of the spool within the driven member during rotation of the driven member.

Abstract: A portable rotary snow thrower is disclosed. The housing of the snow thrower is baffled to cause the snow to be thrown to one side for a particular direction of rotation of the rotor. The rotor may also be rotated in the opposite direction to throw the snow to the opposite side of the snow thrower through the same opening without repositioning of baffles or other mechanical elements.

Abstract: An improved filament for use in the cutting of weeds and vegetation, wherein the filament is attached at one end to a hub for imparting rotary motion to the filament. The centrifugal force extends the filament radially outwardly from the hub, with the energy of rotation being utilized to sever or cut the vegetation. The filament has a generally centrally disposed axis with an irregular or variant cross-section which fluctuates along the axial length of the filament. The variant cross-section with its fluctuations in cross-sectional area reduce the end or terminal fibrillation of the filament.

Abstract: A water ski rope handle of molded plastic construction with floatation cavities in the handle portion and rope anchoring end caps rigidly secured to the ends of the same which provide for mounting of the rope with the knots in the ends of the rope being recessed to captivate the same and with the rope being angled from the handle to minimize fraying or wear thereof.

Abstract: A visual marker means for attachment to the floatation gear of a water skier to enable the skier to be more readily detected when down in the water. The marker means includes a staff having a flag member secured to the upper end thereof, and attachment means are secured to the lower end of the staff to permit releasable attachment of the staff and flag member to the floatation gear of the water skier. The attachment means includes a resilient belt or strap member which is coupled at its upper end to the staff, and at its lower end to the staff securing buckle or plate, the attachment being such that the belt and the staff form a closed loop for the attachment of the safety flag to the floatation gear of the skier.

Abstract: An optically brightened fishing line consisting essentially of a mixture of one or more nylon polymers and a polymer which is the reaction product of a nylon monomer or polymer and a substituted triazine and coumarin component, the substituted triazine and coumarin component having the structural formula: ##SPC1##The substituted triazine and coumarin component is present in a reactant mixture in the range of from about 0.01 mol up to about 0.25 mol per mol of nylon monomer, with the reactant mixture being treated so as to form a reactant mass which is active in performing a variety of functions when reacted with nylon polymers or mixtures of polymers. Thereafter, the reactant mass is mixed with one or more nylon polymers, with the reactant normally being present in the range of about 0.1 up to about 15% by weight.

Abstract: An improved line bail structure for spinning reels wherein the line bail comprises a generally resilient semicircular arm coupled to the reel rotor with the ends of the bail being stressably offset along a plane parallel to the axis of the spool spindle and also along a plane perpendicular thereto to provide torsional stresses which effect stable open and stable closed bail dispositions. The bail is coupled to the rotor through a plunger element which is adapted to automatically control the rockable rotation of the bail between open and closed dispositions upon winding. Stop means are formed along the plunger to define the stable limits for the open and closed dispositions of the bail, and with a camming ramp being secured to the reel frame to automatically rockably shift the line bail from open disposition to closed disposition upon winding and consequent rotation of the rotor.

Abstract: A fishing reel, particularly a fly fishing reel, which is provided with an auxiliary drag assembly actuated by finger pressure exerted radially inwardly on the assembly. The reel includes a line receiving spool with the spool flanges having an outer peripheral edge defining a braking surface. The frame means includes a circular spool retaining ring comprising first and second concentrically disposed arcuate sectors, with the arcuate sectors having a substantial degree of arcuate overlap wherein one of the sectors is provided with an arcuate cantilevered segment which may be forced inwardly by finger pressure to make contact with the outer edge surface of the spool flange so as to generate frictional drag resisting free rotation of the line spool within the frame.

Abstract: A multi-filament rope which comprises a blend of filaments braided together to form a composite line structure. The core of the structure consists primarily of polyimide of an aromatic tetracarboxylic acid dianhydride, with the sheath consisting primarily of polyolefin fibers selected from the group consisting of polypropylene and polyethylene braided over the core.

Abstract: An open-face spinning reel having a conventional line spool assembly, spool cap means, and line bail means, the reel structure being further provided with an adjustable drag mechanism for controllably adjusting the rotation of the line spool upon the spindle shaft. The drag assembly includes an indicator bezel which is arcuately fixed to the spindle shaft. A drag adjustment knob means threadedly engaged upon the spindle shaft applies a drag force against the indicator bezel and the drag assembly, the adjustment knob means having indicia cooperatively arranged with indicia on the indicator bezel so as to provide for an absolute indication of the force being applied to the drag assembly and accordingly the amount of frictional force resisting free rotation of the line spool.
